inferred, may take the form of a door, af

' gate, a window, a Hap or something of an analogous'character. Thesupporting-body for the swinging member of whatever .nature the same maybe, may vary decidedly in nature, depending upon the particular use towhich the article is to be put. I have found the invention as highlyadvantageous when incorporated in or forming part of a cabinet or bonsuch as used in sectional bookcase equipment and with show cases. The'swinging element may move in any desired direction; that is it may movehorizontally, vertically or obliquely to either of the other directions.f f l' @ne of the primary bjects of the invention is the provision of anarticle of the character described by which a swinging member such forinstance as a door, can be e'e'ctively mounted and can be opened orclosed without binding in either direction and with a minimumexpenditure of power.

The device possesses other features of novelty and advantage, which withthe foregoing will be stated at length in the followlng descriptionwhereinIwill set forth 1n detail that form of the embodiment of theinvention which -I have selected for illustration in the drawingsaccompanying and forming part of the present specification.v I-doy notlimit myself to this disclosure; I may d epart therefrom in severalparticulars within the scopeof the invention defnei by the claimsfollowing said description.

Referring to said drawings: Figure 1 is a sectional view on the line 1-1of Fig. 5,

Vlooking in the direct-ion of the arrow, the

swinging element represented 'as a door, being shown in the upper dottedline position in its maximum open position and in thelower dotted lineposition as being dismounted. Fig. 2 is a practically similarV viewshowing the door also dotted and as occupying an intermediate position.Fig. 3

is a .cross section on the line 3 3 of Fig. 2,

.looking in the direction of the arrow. Fig.

I4 is an end elevation of a cabinet or show case equipped with a mountinvolving the inventlon. Flg. 5 is a front elevation of the same.

Like characters refer to like parts throughout the several views,whichfare on different scales. As 'already noted I can use the inventionin widely-different connections. In Figs. 4 and 5 I have shown, acabinet 2 presenting a suitable supporting body for the swinging Vpart 3which as shown consists of a door' Aadapted when shut to close the openfront side of the cabinet or case 2 and when open to uncover saidopening as will hereinafter more particularly appear. The cabinet orcase 2 need ,not set as shown. It can be arranged so that what is nowthe back in Fig. 4 would present the bottom,and in this event the door 3or equivalent part would be at the top. In other words I wish to make itclear that I do not limit myself to any particular disposition of thedoor or equivalent, and I have cited 'two of many illustrations vinwhich the same can be arranged to swing.

The swinging member is provided with laterally-extending studs and thesupport- Ying body hasl grooves to receive lthe studs,

the grooves being so shaped as to jointly applya camming and guidingaction to and to also properly support the swinging member Whether thesame be in the form of a door or otherwise. Preferably the studs areduplicated at opposite ends of the door and necessarily the grooves arealso duplicated, each groove being adapted to receive a stud Theconstruction of the studs is not a matter of consequence. As

shown they are plain, butthey might be provided with anti-frictionrollers or equivalent means, the invention not concernmg these andsimllar detalls.

On what is shown as the ends of the doorv the stud' 6 j depthwise of'fthe door. Within the cabinet or case `2 and in opposite walls thereof,(thevend walls as shown) are cam and guiding grooves 8 and 9, 10 and 11,the grooves 8 and 10 being mates and being directly opposite each other,while the grooves 9 and 11 are alike and are also opposed. Thel grooves8l and 10receive for sliding movement the pins or studs 4 and 6', whilethel longer grooves 9 and llreceive for corresponding motion the pins orstuds 5 and 7. 'As illustrated both grooves aro of cam shape and as alsohaving ineffective portions, so that thevwalls of onepair of oppositegrooves may at one time be performin'g a camming action, whilesimultaneously the walls of theI other .two grooves mayl be simplyguiding and vice versa. The shape of the two grooves may be varieddecidedly. As shown the grooves 8 and 10 are formed first on an arcwhich merges into an arc of still greater radius, the innerv terminalportions of said grooves being projected at an angle to the respectivebodies' and the said projecting portions being open as at 12 for areason that will be hereinafter described. With the'grooves 9 and 11they first have a descending portion 9', then they merge into thearcuateportion of largeV radius and finally extend at right angles tothe majorpart of their length being also vopen as at 13. The purpose ofthe open inner ends 12 and l13 of the two sets of grooves is tofacilitate the dismounting of the swinging part 3 as will hereinafterap'- ear. p Normally or when the door 3 is closed the two sets of pins 4and 5 and 6 and 7 will be at the forward or closed ends of the two setsof grooves. To open the door 3 the following procedure may be adopted;the knob or finger piece 14, preferably removably mounted for a reasonthat will hereinafter appear as by furnishing it with a screw threadedshank, is grasped and the door swung forward. Initially or until thestuds or pins 5 and 7 leave the first portion of the mating grooves 11,the motion of the door will be simply a swinging one. Beyond this pointas the door is manipulated, its upper portion is swung into the cabinetor case 2 and at the same time there is a slight lifting motion impartedby the cam portionsofthe two sets of grooves 10 and 11 until the doorhas practically reached its extreme upward movement after Ywhich pointthe upward movement ofthe door is comparatively slight or until whatmight be considered in the illustration given, the lower cross bar ofthe door is practically against the top of the cabinet 2 at which timethe knob, presenting a suitable stop,

acts against the cabinet or case 2 to prevent further inward movement ofthe door. To dismount the door the knob 14 is taken from place and thetwo sets of pins pushed lsaid support.

2. The combination of a swinging member and a support therefor, theswingingV member having projecting studs and the support having groovesto slidingly receive out of the open inner endsI 12: and 13 of thetwopairs of grooves. cases where one set of grooves and studs may beomitted.

YIt willbe .clear that my device comprises 'the duplicate grooves havingbearings for two opposite studs and the forward portions of the othertwo grooves being shaped to positively prevent transverse and to permitsolely swinging motion of the' swinging member when the same leaves itsinitial position or when it substantially leaves said support, and theseveral groovesv being shaped to jointly swing and move the swingingmember transversely on thrust applied thereto, when said swinging memberleaves ,said support. In. the present case the bearings inquestion lareobtained by closing the forward ends of the .grooves 8 and 10, so thaton the primary movement of the swinging member 3, the studs 4 and 6vcanturn against said closed endsat which time the upper studs 5 and 7travel in the' forward arcuate portions 9 ofthe grooves 9 and 11. When Ispeak of transverse motion of the swinging member 3 I mean what would inthe construction shown be a depth? wise movement thereof.

What I claim is:

There may be '1c The combination of a swingingmem#v V ber and a supporttherefor,` the swinging member initially fitting within the support andhaving projecting studs arranged in pairs, the studs of the respectivepairs being opposite each other and the support having grooves arrangedin lduplicate pairs to slidingly receive the respective pairs of studs,the forward ends of two of the du? plicate grooves having bearings fortwo op-v posite studs and the forward portions of the other two groovesbeing shaped to positively prevent transverse and to permit solelyswinging motion of the swinging member when the same leaves its initialposition and passes substantially out of said support and the severalgrooves being shaped to jointly swing and move theswinging membertransversely on thrust applied thereto, when said swinging member leaves.ing member, the rear endsl `of said grooves mme@ being open to permitdsmounting of the swinging member, and an operating member on theSwingin member for engaging the support when t e swingingmember is 5wide open, said operating member being removably mounted.

In testimon whereof aix my signature Witnesses: v
